      <bold>Dear Editor,</bold>
    </p>
    <p>Heart failure (HF) has become a major public health problem, as it is the final pathway of most heart diseases<xref ref-type="bibr" rid="B01">1</xref>. One of the main factors that lead to decompensation in HF is poor patient adherence to treatment<xref ref-type="bibr" rid="B02">2</xref>.</p>
    <p>Educational intervention programs for the management of chronic disease and clinical monitoring of HF are associated with better adherence to treatment<xref ref-type="bibr" rid="B03">3</xref><sup>,</sup><xref ref-type="bibr" rid="B04">4</xref>. It was observed, in a non-controlled clinical trial with 25 patients in a HF outpatient clinic, that the educational intervention improved the following indicators: renal function assessment with improved estimated glomerular filtration rate (eGFR; median: V0 = 61 vs. V1 = 68) and B-type natriuretic peptide (BNP), treatment adherence score and functional capacity at the six-minute walk test (6MWT). The treatment adherence questionnaire assessed the following: correct use of medications, daily weight, salt and fluid restriction, alcohol intake and attendance at appointments and tests. The adherence score can range from zero to 10 points<xref ref-type="bibr" rid="B04">4</xref>. At the adherence assessment, an improvement was observed comparing the pre (V0) and post (V1) intervention periods, with a median of V0 = 5.0 <italic>vs</italic>. V1 = 6.1 (p = 0.006). It was demonstrated that in V0, the patients considered non-adherent sought the emergency service in the last 30 days more often than those considered adherent (p = 0.013) and in V1, 100% of patients reported not having sought the emergency service during the period. After the educational intervention, patients with systolic HF with low left ventricular ejection fraction (LVEF &#8804; 40%) showed improved adherence score (p = 0.006) and clinical improvement with a decrease in functional class (FC) and weight (p = 0.022). As for the 6MWT, the patients that showed better performance in the test were those considered adherent to treatment, with FC III, time of HF = 12-16 years, LVEF of 24 to 29%, and hypertensive etiology. Clinical and renal function improvement was observed in outpatients with heart failure submitted to educational intervention that showed greater adherence to optimized therapy.</p>

Um dos principais fatores que levam &#224; descompensa&#231;&#227;o na IC &#233; a baixa ades&#227;o dos pacientes ao tratamento<xref ref-type="bibr" rid="B02">2</xref>.</p>
      <p>Programas de interven&#231;&#227;o educacional para o manejo da doen&#231;a cr&#244;nica e monitora&#231;&#227;o cl&#237;nica da IC est&#227;o associados a uma melhor ades&#227;o ao tratamento<xref ref-type="bibr" rid="B03">3</xref><sup>,</sup><xref ref-type="bibr" rid="B04">4</xref>. Observou-se, em um ensaio cl&#237;nico n&#227;o controlado com 25 pacientes de um ambulat&#243;rio de IC, que a interven&#231;&#227;o educacional melhorou os seguintes indicadores: dosagem de fun&#231;&#227;o renal com melhora da taxa de filtra&#231;&#227;o glomerular estimada (TFGe; mediana: V0 = 61 vs. V1 = 68) e pept&#237;deo natriur&#233;tico do tipo B (BNP), escore de ades&#227;o ao tratamento e capacidade funcional pelo teste de caminhada de 6 Minutos (TC6'). No question&#225;rio de ades&#227;o ao tratamento, foram abordados: uso correto dos medicamentos, peso di&#225;rio, restri&#231;&#227;o de sal e l&#237;quidos, ingest&#227;o de bebida alco&#243;lica e assiduidade em consultas e exames. O escore de ades&#227;o pode variar de zero a 10 pontos<xref ref-type="bibr" rid="B04">4</xref>. Na avalia&#231;&#227;o da ades&#227;o, foi observada melhora comparando-se o per&#237;odo pr&#233;- (V0) e p&#243;s-interven&#231;&#227;o (V1), com mediana de V0 = 5,0 vs. V1 = 6,1 (p = 0,006). Evidenciou-se, na V0, que os pacientes considerados n&#227;o aderentes procuraram o servi&#231;o de emerg&#234;ncia nos &#250;ltimos 30 dias com mais frequ&#234;ncia que os considerados aderentes (p = 0,013) e, na V1, 100% dos pacientes relataram n&#227;o ter procurado a emerg&#234;ncia no per&#237;odo. Ap&#243;s interven&#231;&#227;o educacional, os pacientes com IC sist&#243;lica com fra&#231;&#227;o de eje&#231;&#227;o do ventr&#237;culo esquerdo baixa (FEVE &#8804; 40%) apresentaram melhora do escore de ades&#227;o (p = 0,006) e melhora cl&#237;nica com diminui&#231;&#227;o de classe funcional (CF) e perda de peso (p = 0,022). Quanto ao TC6', os pacientes que apresentaram melhor desempenho no teste foram aqueles considerados aderentes ao tratamento, com CF III, tempo de IC de 12 a 16 anos, FEVE entre 24 e 29%, e etiologia hipertensiva. Foi observada melhora cl&#237;nica e da fun&#231;&#227;o renal nos pacientes com IC ambulatoriais submetidos &#224; interven&#231;&#227;o educacional que apresentaram maior ades&#227;o &#224; terap&#234;utica otimizada.</p>
